Number of persimmons that Japheth used
=
45 x 190
= 152
Number of persimmons that Japheth had left
= 190 - 152
= 38
Number of oranges that Japheth used
=

= 168
Number of oranges that Japheth had left
= 192 - 168
= 24
Fraction of the fruits left that were oranges

18=
78 Number of persimmons left = 1 u = 38
Number of oranges left in the end
